Thanks for this video. It is really insightful!

I also have to thank you for this. It is a lot of fundamental and subtil concepts which are packed in this 20 min + videos.

I'm sure you're probably getting tired of hearing this, but thank you! I've been through the Fundamental Optical Design book, Coursera's/UC Boulder's online certificate program, pencilofrays, Jena lectures, just about every RUclips video I could watch on this stuff, forums, and your videos have been, by a very large margin, the most helpful. It's insane how advanced optical engineering is, but you manage to cherry pick exactly what is important, and share it in a way anyone can understand. For me, I think we both know, I still don't know lens design, but I feel your videos have put me in a position to at least start on lens design, encounter those road blocks, figure out how to overcome those obstacles, and learn how you're supposed to. This is in stark contrast to what usually feels like being taught an entire language, with all the nuance, and having no idea it's for communicating. Just a breathe of fresh air watching these videos, kudos to you man! Hope you're enjoying your retirement!! You deserve it.

Great video. Thank you very much! Am I correct to say that if the lens I'm designing only concerns a very narrow field of view, then it is ok to use a simple relay lens e.g. an achromatic pair?

Great videos to connect optics knowledge with a software. Thank you for sharing back your knowledge. Please kindly post : when is part3:Mobile phone lenses coming. Also Please cover A- Telecentric lenses along with use of features in Zemax system explorer like how to correctly setup AFocal system, telecenteric lens... B- please have video on Optimization tab features what each means and C- please go through Analysis tab on what each features mean. Thank you so much

Hi,Mr Mark Can you help me please to check my system correctly?

🎉amazing 👏

Wow, outstanding videos, and what I was looking for. Thank you for sharing, my photography and lens understanding journey just got some better "illumination".

With the likes of an air spaced doublet, do you actually need the large refractive index difference between the air and the glass? Or might you be able to use an intermediate index optically transparent medium like an immersion oil or Canada balsam to help reduce reflections? Perhaps a balsam type cement would also mechanically secure required placement.

Is there readily available software to make lenses on a CNC machine (similar to how freeform spectacle lenses can be made)?

thank you for the videos! is it possible to download these sketches in high quality somewhere?

wonderful! thank you very much

sir if the object close to lens or object as a self luminous components like an LED then which type of aperture will use ?

waiting for your wide angle lenses tutorial

Listen man. Getting taught by the ex-CEO, completely free, as an undergraduate student in applied physics, is of immeasurable value. A big thank you!

Thanks for the video mark!

Thank you very much for such a great video! Waiting for a similar one talking about the condenser lens ;)

Hi Mark, Thanks for the wonderful video. Can you please do a video on the design of microscope objective lenses?

Thank you for wonderful lecture!! Hope you post again

Hope you can post more videos like this!

Such a great video. Thank you!

Welcome back after 2 years!🎉 Great video. Thanks for the explanation!

Well done!

Very helpful. Thank you! very much

Thank you very much for your video! It's very helpfull!

Hi sir, Can you please share all the slides provided in summary part of the video, it will help us to practice in real life and follow your notes step by step. Thanks !!

Hi Mark, this is a great video not only in the main substance but also in the nifty tricks.. I just watched this video but I'll watch all of your videos for sure. I also have a specific question re cooke triplet. Is it possible to design a cooke triplet with about 100x demagnification, let's say taking object size of 20 mm and making it 0.02 mm. The design does not have to be necessarily compact. I'm just wondering if there is a principle problem with this much magnification power. As far as I can tell, for cooke triplet to work, it needs to somehow have some symmetry in power of the lenses and this would make it not a good design for high magnifications. Thanks!

Is there any constraint which tries to restrain the desired fov in the given detector size or at image surface? If any can you suggest the operand. Thanks.

If softwares like zemax can optimise and give rise to best possible lens then why one need to add multiple lenses why can't we work with single lens as the ultimate goal is to have proper focus?

Hi, I am new to Zemax, I just got a job ( first after my PhD) as an optical engineer working with microscope designs. Question: (1) what fits better to my new profession Zemax or Zemax OpticStudio or maybe there are the same; (2) which tutorials I should watch at the beginning - any suggestions? thanks

This series is amazing, would love to see more of it. I've been always curious on how a focusing system is designed for a lens to be able to used effectively at landscape and portrait distances.

You didn't explain how was the merit function prepared

Hi Mark, thanks for these videos. Did you post Part 3: Mobile Phone Lenses? Thanks

So, as I understood it, the number of rings is set to 5 because the optimizer can use higher degree aberrations to compensate for the lower ones, and for this reason, an attempt to control the aberrations manually would not be as efficient as when done by the automatic optimizer. Thank you for the video. It's really appreciated!

Dear Mark, very nice videos. I watched them all and learned a lot. Don't you have plans to make some videos about tolerance?

such an underrated channel.

fantastic overview! thanks! just discovered your channel! as a young aspiring optics designer this is a real treasure trove!

Excellent series,Hope you can update more videos！！！！

Mark, what's going on? Why no more tutorials? Will you be back?????

Beautifully described.... Nice to see you here Mark

Mark, I am grateful for your guidance. Such a great series in optics and practical design. this is the third time I watch all of your videos. hope to see more coming soon. Thank you !!!

Great help for beginners like me！

Very nice videos

I was not able to reproduce your results after optimization. I think I reproduced your original file accurately. Any suggestions. Can you look at my original file?

What wonderful insights. Thank you!!

Please a video optimizing the Tessar lens

Hi Mark! I tried to make magnifying lens with the lens data on your video but the radius of the 3rd surface keeps changing to "Infinity" after I give the value -180.11|F. Why is that happening? Please help me.

I am really grateful that a channel like this exists, for an amateur hobbyist this really accelerates my understanding for experimentation. Lots of nagging questions answered in one. I hope you do more!

Thank you for such a great initiative. I would like to zoom lens design with off-the-shelf lenses. How to start with the chosen lenses and how we can substitute a different lens to have a better performance. Or in general optimization of imaging systems with off-the-shelf lenses.

This video and the next one are part of "extra materials" in an Optics Studio training I am doing. You do an amazing job Mark, this videos are excellent! Thanks so much for your contribution to my learning! Looking forward to watching the rest of your videos.
